Normal operating sounds
When your air conditioner operates nor-
mally, you will hear sounds such as:
l Pinging or clicking as water droplets hit the
condenser. Water droplets help cool
the condenser.
l Air movement from the fan, especially on
QUICK COMFORT setting.
l Clicks from the cooling cycle.
Sounds may also be caused by house
construction - such as vibration of the unit
due to wall construction or an unsteady
window mounting area.
